A device for positioning at least one functional element having a hub for a shaft in a predefined angle position on the shaft includes at least one holder for receiving at least one functional element. The device may include a tailstock or coaxially aligning the shaft in relation to the hub of the at least one functional element. The tailstock may include a centring cone for receiving the shaft. The centring cone may be axially displaceable in relation to the tailstock. The tailstock may include radially expandable centring elements for centring the functional element. The centring elements may assume a defined position against the hub of the functional element in an extended position. The device may also include a movable guide block for moving the shaft.
