1. A transfer device for limiting the twisting of a set of at least one link between a first end of the link, configured to be secured to a fixed part of a rotary device, and a second end of the link, configured to be secured to a revolving part of the rotary device, the revolving part being able to revolve with respect to the fixed part about an axis of rotation (x), the transfer device comprising:
a composite drum comprising a set of drums aligned on the axis of rotation (x) about which the link can be wound, the set of drums comprising a fixed drum intended to be secured to the fixed part in rotation about the axis of rotation x, a revolving drum intended to be able to revolve about the axis x with respect to the fixed part and a set of at least one loose drum interposed between the fixed drum and the revolving drum, each loose drum being free to rotate about the axis of rotation (x) with respect to the revolving drum and a fixed drum and having a height on the axis (x),
transfer means comprising at least one transfer assembly, each transfer assembly being configured to transfer a link of the set of at least one link, when it is wound around the composite drum, between the fixed drum and the revolving drum, to the revolving drum when the revolving drum revolves in a first direction about the axis of rotation (x), and in reverse when the revolving drum revolves in the reverse direction,
wherein the transfer means are configured so as to allow all of a useful winding (U) to be transmitted from the set of at least one link produced continuously around the fixed drum and each loose drum, to the revolving drum so that the useful winding (U) is produced around the fixed drum and each loose drum continuously, when the revolving drum revolves in the first direction, and in reverse when the revolving drum revolves in the reverse direction.
