A coupled state versus a decoupled state of a part relative to a machine, in particular of a coordinate measuring device or a machine tool, is determined. The part to be coupled can be moved toward a contact region of the machine in an axial direction in order to establish the coupled state, and can be moved away from the contact region in the axial direction in order to establish the decoupled state. A magnetoresistive sensor is used to generate a sensor signal that depends on an axial position of the part and a further sensor signal that depends on a rotational position of the part relative to the machine. The sensor signals are evaluated and the result is used to determine whether the part is coupled to the contact region of the machine and/or whether the part is decoupled from the contact region.
