1. A force transmission device for power transmission between an input and an output, comprising:

  • at least an input (E) and an output (A); and

    a vibration damping device disposed in a cavity that can be filled at least partially with an operating medium, the vibration damping device coupled with a rotational speed adaptive absorber,wherein the rotational speed adaptive absorber is tuned as a function of an oil influence to an effective order qeff, which is greater by an order shift value qF than an order q of an exciting vibration of a drive system.
