The invention relates to a device for transmission of movement from a moving object to another object with a differing speed of movement or the reverse, in particular a fluid clutch, characterised in that the other object, in particular a metal surface of an object made from a metal, facing a clutch plate is provided with a thin torque transmission layer, preferably applied by deposition and/or conversion comprising particles or crystals or amorphous material of an oil-insoluble deposit bonded to the metal surface made from phosphates, molybdates, titanates, zirconates, vanadates, tungstates, oxides, hydroxides and/or (basic) carbonates of metals of the second periodic main or sub-group of iron, manganese and/or cerium or with poly(oxy)silane.
