1. A flexure assembly that defines an axis, wherein the axis defines an axial direction, a circumferential direction, and a radial direction, the flexure assembly comprising:
a first spiral flexure that comprises an annular body comprising a central opening coaxial with the axis and a plurality of slots circumferentially-spaced about the axis and axially-extending therethrough;
a second spiral flexure that comprises an annular body comprising a central opening coaxial with the axis and a plurality of slots circumferentially-spaced about the axis and axially-extending therethrough;
a first spacing element positioned between the first spiral flexure and the second spiral flexure;
a second spacing element positioned between the first spiral flexure and the second spiral flexure;
a first plurality of fasteners circumferentially-spaced around the axis, wherein each of the first plurality of fasteners axially extends through radially inner portions of the first spiral flexure, the first spacing element, and radially inner portions of the second spiral flexure;
a second plurality of fasteners circumferentially-spaced around the axis, wherein each of the second plurality of fasteners axially extends through radially outer portions of the first spiral flexure, the second spacing element, and radially outer portions of the second spiral flexure;
a first plate; and
a second plate,
wherein the first spiral flexure, the first spacing element, the second spacing element, and the second spiral flexure are each positioned between the first plate and the second plate, and
wherein each of the first plurality of fasteners extends through either the first plate or the second plate, but not both, and each of the second plurality of fasteners extends through the other of the first plate or the second plate, but not both.
