<p>A clutch mechanism which is for selectively transmitting drive a driven member has operating means (13) for changing the state of the clutch (10, 12) between operative and inoperative positions. There is also an actuator (16) for energising the operating means and mechanically operated means (14) for transmitting drive between the actuating means and the operating means. The transmission means includes cushioning (10, 30; 40) whereby during phases of the operation of the clutch the tansmission means transmits drive to the operating means at different rates whereby to extend the range of movement at the bite point of the clutch.</p> |
