Abstract

A torque transmission device for a powertrain of a motor vehicle has an input area and an output area. A torque path runs from the input area to the output area. A torsional vibration damping unit is positioned first, followed by a gear unit, along the torque path between the input area and the output area. The torsional vibration damping unit provides a first spatial area and an adjoining second spatial area along the torque path, and the gear unit provides an adjoining third spatial area.
