Abstract
A failsafe module comprising an input member (), an output member (), and a coupling mechanism for coupling the input member to the output member. The coupling mechanism comprises an intermediate member () movable relative to the output member to energise an energy storage device and a latch mechanism () to hold the energy storage device in an energised state. When the latch mechanism is engaged, the input and output members are coupled together and the energy storage device is held in an energised state and isolated from the coupling between the input and output members. When the latch mechanism is released, the energy storage device can release its energy to drive the output member to a predetermined position.
