Claim 3:
4. The failsafe module according to claim 3, wherein:
the input member and output member both comprise surfaces extending parallel to the common axis;
the axial surface of the input member defines a circumferential edge extending radially across the axial surface of the input member;
the axial surface of the output member defines an axial edge extending radially across the axial surface of the output member;
the input member and output member are nested and arranged such that the circumferential edge and the axial edge are angled relative to each other and overlap in the radial direction;
the intermediate member comprises an arm extending radially across the circumferential edge and the axial edge, such that movement of the arm is constrained by the circumferential edge and the axial edge; and,
the circumferential edge and the axial edge each have a component parallel to the common axis, such that when the input member is rotated relative to the output member, the constrained movement of the arm by the circumferential edge and the axial edge forces the intermediate member to move linearly relative to the output member between the first and second positions.
