Abstract
A solid core (3) serves to transmit both torque and axial thrust (if any) between first and second end pieces (1 and 2) having longitudinal axes that may be up to 10.degree. out of alignment. The core is close to being cubical in shape, having two interfitting sets of three adjacent sides each comprising a first semicircular plane face, a semi-cylindrical face, and a second semicircular plane face. Concave recesses (10, 13) are provided in respective front faces of the two end pieces to receive each of the semi-cylindrical surfaces of the core. The 'chunky' nature of the core maximizes the torque that can be transmitted in a given volume.
