A transmission system is disclosed for the contactless transmission of at least one electrical and/or electromagnetic signal from a first device part of a data-generating device to a second device part of the device by way of electrical and/or electromagnetic coupling. The first device part is set up to perform a movement relative to the second device part during operation. The transmission system includes a first transmission unit and a second transmission unit, either being arrangable on the first device part and the other being arrangable on the second device part. The first transmission unit includes a first coupler and a first auxiliary coupler and the second transmission unit includes a second coupler. For the electrical and/or electromagnetic coupling, the coupling strengths between the first coupler and the second coupler and between the first auxiliary coupler and the second coupler have different functional distance dependences.
