Hydrodynamic coupling device, in particular a torque converter

A hydrodynamic coupling device, comprising:

• a housing arrangement for filing with a fluid;
• an impeller which is rotatable with the housing arrangement around an axis of rotation;
• a turbine which is arranged in the housing arrangement and which is rotatable with a driven member around the axis of rotation;
• a lockup clutch for producing a torque transmission connection between the housing arrangement and the driven member;
• a torsional vibration damping arrangement including an input region and an output region;
• a first torque transmission path provided between the input region and the output region;
• a second torque transmission path parallel to the first torque transmission path and provided between the input region and the output region;
• and
• a coupling arrangement superposing torques transmitted via the first and second torque transmission paths, wherein the torsional vibration damping arrangement includes a phase shifter arrangement in at least the first torque transmission path, the phase shifter arrangement generating a phase shift of rotational irregularities transmitted via the first torque transmission path relative to rotational irregularities transmitted via the second torque transmission path, wherein the coupling arrangement comprises a planetary transmission arrangement.
