Abstract
A coupling device with two coupling members, which are to be connected coaxially together, and a tension rod, which penetrates the first coupling member and is to be coupled with the second coupling member. To minimize the effect of the cross forces on the positioning of the second coupling member, it is provided that the end, facing the head of the tension rod, penetrates into a passage borehole of the second coupling member with a radial clearance; and a connector, resting against a shoulder of the second coupling member, can be attached to the end, thus resulting in radial clearance between connector and second coupling member. Furthermore, a connector is described whose periphery has a contour, which prevents a turning action inside the coupling member, whereby the connector can also be moved in the coupling member and exhibits an axial contact surface, which is adequately small to enable a swivelling motion without generating a counteracting moment of flexion.
