The invention relates to a device for rotatably coupling two coaxial connection elements, of which at least one is configured as a circular ring, and which each have at least one annular surface that faces the respective surfaces of the other connection element but that is positioned at a distance from said respective surface by a gap such that the coaxial connection elements can be rotated in opposite directions about an imaginary axis (rotating axis) that is approximately perpendicular to the ring plane and located in the center of the annular connection element. A rotational bearing configured as a single or multiple-row anti-friction bearing is disposed in the gap between the two connection elements, said bearing absorbing axial and radial loads and tilting torques, wherein at least one annular connection element has a circular, plane neck at the surface thereof facing away from the gap, said neck comprising an oblong or elongated cross-section and extending away from the gap up to an open-ended peripheral circumferential edge. |
