Abstract

A device for connecting a blade to a rotor shaft of a continuous flow machine, includes a first fork foot which has a quantity of first foot lugs with first bore holes, a second fork foot which has a quantity of second foot lugs with second bore holes, and at least one connection bolt which passes through first and second bore holes to connect the first fork foot to the second fork foot. The device has a first area with a predetermined first diameter difference between a first inner diameter of one of the bore holes and a first outer diameter of the connection bolt, and a second area with a predetermined second diameter difference between a second inner diameter of one of the bore holes and a second outer diameter of the connection bolt, wherein the first diameter difference and the second diameter difference differ from one another.
