a torsional vibration damper with at least two components that are rotatable relative to each other against the opposition of at least two deformable energy storing elements , such as arcuate coil springs . in order to at least reduce the noise that is generated by the damper , the energy storing elements are connected to each other by at least one coupling device that is designed to ensure that , when one of the energy storing elements is deformed , there results a controlled entrainment of the other energy storing element or elements .
