The starting device comprises a hydrodynamic coupling (1) with an impeller (4) and a turbine wheel (5), which forms a torus-shape with one another. A working fluid filling and discharging working chamber (6) is provided, which is formed with a working fluid supply unit (11) and a working fluid discharge unit (12), in which a circulating flow (7) of the working fluid is formed. An adjusting unit (20) is provided, which comprises a valve formed in a control line (24) or attached in an operating manner. An independent claim is included for a method for varying power transmission in a starting device.
