That is, this Surface areas 30 and 56 each form insertion or Guide inclined surfaces, which also with relative inclination of these two Components ensure that the manufacture of the slewing ring required intermeshing of the areas with non-rotationally symmetrical Circumferential contour can be achieved. This is especially so of importance when in the release position of the first coupling element 18 and the coupling receiving position of the second coupling element 20 the guide section 28 of the first coupling element not or only engages slightly in the opening 52.
