Abstract
A rotor blade coupling device () comprising a torsionally rigid carrier () is disclosed, the carrier () being mounted in a manner which is free of centrifugal force between a thrust bearing () and a control bearing (), resilient impact and pivoting movements of the rotor blade coupling device () being able to take place in a damped manner. The rotor blade coupling device () is clamped between a rotor head star () and a rotor head central piece () and held rotatably about the rotor axis A. The centrifugal forces which occur, are transmitted from a rotor blade holder () to the rotor head star () and thus kept away from the carrier ().
