1. A compensating coupling for connecting a first shaft to a second shaft along a rotational axis, the compensating coupling comprising:
two coupling bodies, including a first coupling body to be connected to an end of the first shaft and a second coupling body to be connected to an end of the second shaft;
at least one elastic coupling element, said at least one elastic coupling element having a first end, a second end, and a longitudinal axis lying in a plane oriented perpendicular with respect to the rotational axis;
said two coupling bodies being arranged relative to one another to form a three-dimensional coupling region in which said at least one elastic coupling element is arranged between said two coupling bodies;
said at least one elastic coupling element being connected to said two coupling bodies to allow a displacement of said two coupling bodies in a radial direction with respect to the rotational axis;
said at least one elastic coupling element being connected to said two coupling bodies to allow a displacement of said at least one coupling element in an axial direction with respect to the rotational axis;
said first coupling body being connected to an end of the first shaft and said second coupling body being connected to an end of the second shaft, such that respective longitudinal axes of the first and second shafts coincide with the rotational axis;
said two coupling bodies being rotationally symmetrical with respect to the rotational axis;
said at least one elastic coupling element being formed of a fiber-reinforced polymer, and said at least one elastic coupling element having a strip-shaped configuration;
said first coupling body having a segment which is configured for connecting said first coupling body to said first end of said elastic coupling element, with the connection being configured to cause the longitudinal axis of said at least one elastic coupling element to lie in a plane perpendicular to the rotational axis;
said second coupling body having a segment which is configured for connecting said second coupling body to said second end of said at least one elastic coupling element, with the connection being configured to cause the longitudinal axis of said at least one elastic coupling element to lie in the plane perpendicular to the rotational axis;
said at least one elastic coupling element including, at one end or at both ends thereof, a metal insert that is laminated in a form of a sleeve into said at least one elastic coupling element;
said segment of said first coupling body having a screw that braces a spacer sleeve, said screw having a head and having a rotational axis;
a disk disposed between said head of said screw and said spacer sleeve, said disk forming an axial stop for said at least one elastic coupling element in a case of an axial displacement;
said laminated-in sleeve of said at least one elastic coupling element being pushed over said spacer sleeve to thereby connect said at least one elastic coupling element to said first coupling body;
said spacer sleeve enabling said at least one elastic coupling element to be displaced in the axial direction extending longitudinally with respect to the rotational axis of the compensating coupling; and
said at least one elastic coupling element being rotatable about the rotational axis of said screw.
