Abstract
The invention relates to a coupling for making a connection secured against relative rotational and axial displacement between a hub member and a shaft member. The shaft and hub members have engaging keys and grooves at the internal and external circumferences thereof. The hub member has a circumferential groove undercutting the keys thereof and an insert member having the same key and groove configuration as the shaft member is disposed therein. The insert member is circumferentially offset relative to the hub member so that the respective keys and grooves thereof are out of alignment. The keys of the insert and hub members are then in axially abutting engagement with the insert member serving as an anchor so that a screw connection between the shaft and the insert members allows the shaft and hub members to be drawn towards each other to form a firm and secure connection.
