Abstract

A device for fastening a casing tube switch module to a casing tube of a steering wheel shaft when a steering wheel is mounted on the steering shaft. The device including a clamping element and a bearing. The clamping element is arranged coaxially between the casing tube and the switch module. The clamping element exerts a clamping force in a direction extending radially out from the steering shaft. The bearing rotationally decouples the steering wheel from the switch module. The bearing has a stator operable for transferring an axial motion of the steering wheel as the steering wheel is mounted on the steering shaft to the switch module such that the switch module moves axially with respect to the casing tube toward the clamping element and tensions the clamping element to apply the clamping force to fasten the switch module to the casing tube.
