A coupling head with a device carrier for the automatic coupling of couplable vehicles is disclosed, wherein the device carrier comprises a plurality of the components necessary for realizing the automatic coupling and/or decoupling. In order to enable assembly/disassembly of these components on the coupling head which is as simple as possible, the device carrier is disconnectably mounted on the coupling head such that at least one of the components will be activated or deactivated during the coupling and/or decoupling. Also disclosed is a method for assembling a coupling head with a device carrier which comprises a plurality of components necessary for realizing the automatic coupling and/or decoupling.
