1. Apparatus for damping torsional vibrations, comprising:

  • input and output members arranged to carry out rotary movements with and relative to each other; and

    at least one damper operating between and arranged to oppose at least some rotary movements of said members relative to each other, said damper comprising at least one energy storing device, wherein said input and output members respectively comprise primary and secondary flywheels, said damper further comprising at least one input element receiving torque from said primary flywheel and an output element rotatable relative to said at least one input element and arranged to transmit torque to said secondary flywheel, said at least one energy storing device being interposed between portions of said at least one input element and said output element to yieldably oppose rotation of said at least one input element and said output element relative to each other, said apparatus further comprising a first torque transmitting connection between said input member and said at least one input element and a second torque transmitting connection between said output element and said output member, said at least one energy storing device being located at a smaller radial distance from said axis than either of said torque transmitting connections.
