Abstract: An inner annular member of the arrangement surrounds the shaft and has an outer circumferential face two sections of which conically taper in mutually opposite directions. The inner annular member is also provided with a radially outward extending collar intermediate these sections. A pair of outer annular members each surround one of the sections with clearance and have an exterior cylindrical surface and an interior surface having a taper opposite to that of the respective section to form therewith a wedge-shaped annular clearance. The outer annular members abut from opposite axial ends against the collar. Tension members are received in the respective clearance and are drawn by both or the like inwardly of the clearance so as to force the inner member against the shaft and to the outer members against the surrounding hub, thus coupling the hub and the shaft for joint movement.
