摘要： A coupling disc (40) is disclosed for coupling a rotating electrical machine to a prime mover. The disc comprises an inner region (42) for connection to a rotating component of the electrical machine, and an outer region (46) for connection to a rotating component of the prime mover, the inner region and the outer region lying in a different plane. The disc further comprises an intermediate region (42) between the inner region and the outer region, the intermediate region comprising a plurality of slots (52). This may allow two or more discs to be stacked together in such a way that interference between the surface profiles of adjacent discs is reduced or avoided. Furthermore, the slots in the intermediate region may reduce the strain placed on the material when forming the disc, thereby facilitating manufacture.
