A rotationally elastic coupling has a first coupling part with elastomers. The elastomers are arranged in the first coupling part in such a way that the elastomers serve to transfer a force onto a second coupling part when the first coupling part and the second coupling part are connected to one another. In order to improve the identification of wear, the rotationally elastic coupling has a switching element that is arranged at least in part in a first elastomer of the elastomers. A method is provided for producing a first elastomer for a rotationally elastic coupling of this kind. A method is provided for identifying a wear state for a rotationally elastic coupling of this kind.
