A clutch plate comprises a friction disc and a hub mounted for relative angular movement within a predetermined range. The hub and friction disc are coupled together by first and second stage dampers, the first being lower rated than the second. Each damper comprises a radial flange, two guide washers on respective sides of the flange and springs interposed circumferentially between each flange and its guide washers. The flange of the first stage damper is defined by one of the guide washers of the second stage damper and the guide washers of the first stage are fixed for rotation with the hub. The clutch plate comprises two subassemblies, one comprising the hub and the flange, guide washers and springs of the first stage damper and the other the flange and other guide washer of the second stage damper, the springs of the second stage damper being preferably part of the other subassembly.
