Torque transmitting device with torque limiting device
A torque transmission device has aligned input and output shafts which are interconnected by two coupling members which are in driving engagement by the input and output shafts for rotation in respective opposite directions. The coupling members have limited relative rotational movement and are biased into engagement with the shafts by a torsion device which extends between them. The arrangement is such that drive is always transmitted through the torsion device, irrespective of direction of rotation. A brake is responsive to relative rotation between the input and output shafts.
