A clutch plate including: a plate assembly comprising axially spaced first and second plates (11,12) and having an annular periphery extending from the first plate to which an assembly of friction material (14, 15) is applied to face in each of opposite directions, a hub for connection to an output shaft, a hub flange positioned between the first and second plates (11,12) and being drivable by the plate assembly (11,12) to rotate, the hub being drivable to rotate by the hub flange, the plate assembly (11,12) and the hub flange being angularly displaceable relative to each other within a predetermined range and being coupled together by at least two drive springs (30, 31), which are positioned equidistantly about the hub, characterised by each of the drive springs (30, 31) being formed by first and second curved compression springs (32, 33) which are arranged in series and which are separated by a straight spring of relatively short length compared to the first and second curved springs (32, 33), the first and second curved springs (32, 33) being of substantially the same length and of a substantially constant radius of curvature and being mounted concentric about the hub so that the drive springs (30, 31) formed by the first and second curved springs (32, 33) and the straight spring are of substantially constant radius of curvature, each of the curved springs (32, 33) being of low torque relative to the straight spring, the drive springs (30, 31) being at least partly positioned between the first and second plates (11,12), each end of the drive springs (30, 31) being in engagement with an abutment of the hub flange and an abutment of the plate assembly (11,12), the drive springs (30, 31) applying a biasing load against relative angular displacement between the plate assembly (11,12) and the hub flange, a sleeve extending about a portion of the length of each of the drive springs (30, 31), the sleeve of each drive spring (30, 31) being formed in two sleeve portions (41, 42) of which a first sleeve portion is disposed about a portion of the length of the first curved spring and the second sleeve portion is disposed about a portion of the length of the second curved spring and whereby a portion of each of the drive springs (30, 31) extends out of the sleeve, and the sleeve being interposed between a radially outer surface of the springs (30, 31) and a facing bearing surface formed by the plate assembly (11,12), the springs (30, 31) being movable within the sleeves relative to the sleeves and the sleeves being movable relative to the bearing surface of the plate assembly (11,12). a plate assembly comprising axially spaced first and second plates (11,12) and having an annular periphery extending from the first plate to which an assembly of

springs (30, 31) being in engagement with an abutment of the hub flange and an abutment of the plate assembly (11,12), the drive springs (30, 31) applying a biasing load against relative angular displacement between the plate assembly (11,12) and the hub flange, a sleeve extending about a portion of the length of each of the drive springs (30, 31), the sleeve of each drive spring (30, 31)

portion of the length of the second curved spring and whereby a portion of each of the drive springs (30, 31) extends out of the sleeve, and the sleeve being interposed between a radially outer surface of the springs (30, 31) and a facing bearing surface formed by the plate assembly (11,12), the springs (30, 31) being movable within the sleeves relative to the sleeves and the sleeves being movable relative to the bearing surface of the plate assembly (11,12).
