ABSTRACT:
A coupling assembly which includes an inflatable annular tube, a plurality of friction shoes removably attached to the tube so that the shoes move radially as the tube is inflated and deflated. The shoes include a friction pad bonded to one side of a backing plate and a driving bar also made of friction material bonded to the other side of the backing plate and joined together in a unitary structure. The driving bars fit into grooves formed in the tube to improve torque transfer between the shoes and the tube.
