Claim Text:
1. A method of forming a spur toothing on a coupling element, the coupling element having a rotational axis extending in an axial direction, and the coupling element having a first section comprising plastically formable material, the first section formed as an annular bead extending in the axial direction from the coupling element, the method comprising the steps of: providing the coupling element having the first section; forming the first section with a die, thereby distributing the material in the die to form the spur Loathing proportionally on an axial end side of the first section; wherein the coupling element comprises a second section which extends in the axial direction from the coupling element and is disposed radially inward of the first section whereby, when the spur toothing is formed, an annular groove is formed between the spur toothing and the second section; and wherein, before the step of forming, the first section is delimited radially by a first contour and a second contour disposed radially inwardly of the first contour which converge on one another radially such that a cross section of the first section narrows along the axial direction.
