Abstract: A flexible coupling (12, 16) for transmitting torque from a drive shaft (10) to a driven shaft (18) is described. The coupling (12, 16) comprises a rotatabledrive member (20) securable to the drive shaft (10); a rotatable driven member (22) securable to the driven shaft (18); a plurality of radial vanes (24) are provided on the drive member (20) which interdigitate with a plurality of radial vanes (26) on the driven member (22) and resiliently deformable elements (30, 32) are interposed between the interdigitating vanes (24, 26) to transmit torque there between. The resiliently deformable elements (30, 32) are detachably secured to only either the vanes (24) on the drive member or the vanes (26) on the driven member and are removeable in a radial direction without having to remove the drive or driven vanes from the coupling.
