Abstract
A lock-up clutch for a fluid coupling has a rotating casing having a radial wall which is releasably coupled by the clutch to a piston. The wall is in a fixed axial position; the piston is arranged for relative axial displacement and is coupled to the wall by tongues. Fastening shanks extend through holes in the piston and holes through the ends of the tongues. A friction wedge is interposed between each tongue and the piston, thus preventing radial displacement of the tongue with respect to the piston after the piston has been secured on the fastening shanks (by means of fastening sleeves).
