1. Device for the protection of a shaft of a test bench from contact with an enclosure, which is provided for the accommodation of at least part of the shaft, wherein the enclosure is closed in the circumferential direction and comprises an inner surface facing the shaft, which inner surface is set up to be arranged in a contactless manner relative to the shaft in an intended position of the shaft, wherein at least two conductor loops are arranged on the inner surface, wherein the conductor loop, respectively each conductor loop of the at least two conductor loops is coupled to a measuring device, which in each case is set up to cause an electrical signal to be transmitted through the conductor loop, and to detect an interruption of the electrical signal, wherein the enclosure is composed of an upper half-shell and a lower half-shell, wherein the upper half-shell is mounted on the lower half-shell, and wherein one conductor loop of the at least two conductor loops is arranged on the inner surface of the upper half-shell, and one conductor loop of the at least two conductor loops is arranged on the inner surface of the lower half-shell.
