Claim 16:
17. The failsafe module according to claim 1, further comprising:
a collar comprising an inner part having an axially extending aperture, and an outer part extending radially outwardly from the inner part and substantially around a portion of the circumference of the inner part, whereby the collar is configured to fit around a portion of the input member, such that the input member and the collar are co-axial about a common axis, and the input member and collar are rotationally fixed, when the collar is fitted to the input member; and, a stop located in the rotational path of the outer part when the collar is fitted to the input member, such that rotation of the collar relative to the stop causes a circumferential end of the outer part to engage with the stop, thereby limiting the range of rotation of the collar and thereby the input member;
wherein the outer part comprises a first circumferential end configured to engage with the stop before the energy storage device is energised, thereby preventing rotation of the input member in a first direction while the energy storage device is not energised; and wherein the outer part comprises a second circumferential end configured to move towards the stop as the energy storage device is energised by rotating the input member in a second direction, and whereby rotation of the input member in the first direction and the second direction is permitted by the collar once the energy storage device is energised and the latch mechanism engaged; and
wherein the aperture comprises a lip configured to interlock with a corresponding indent on the input member when the collar is fitted to the input member, thereby preventing relative rotation between the input member and the collar.
