The rotor (21) can be arranged directly on a clutch bell (13) of the clutch device (8).

The invention further relates to an assembly element (5) with adjustable pretension.

A permanently elastic spring member (7) is interposed between a bell-shaped fitting (10) and the assembly element (5).

The rotor (21) can be arranged directly on a clutch bell (13) of the clutch device (8).

In the operating mode, the coupling element (1) is connected by a vacuum line (8) with a vacuum tank (9) which can hold all the water from a batch of yarn is located on a support block (5) over which a dome (4) is placed.

The coupling portion includes an interior surface that includes a coupler pocket.

The coupling device includes a coupling device opening and a flange positioned adjacent to the coupling device opening.

More particularly, a shoe heel comprises a coupling member that includes a coupling end integrally formed with an end of a coupling rod.

A coupling element of the coupling device comprises a fixing pin for engaging in a locking groove on the other coupling element.

The coupling mechanism includes a first coupling member, a second coupling member and a drive source.

The locking unit comprises a coupling lever pivoting between a coupling position and a release position of the coupling pin.

The coupling comprises a first and second coupling portion, with the second coupling portion rotatable relative to the first coupling portion.

The coupling device includes a first coupling unit and a second coupling unit which is engaged with the first coupling unit to receive driving force.

A permanently elastic spring element (7) is positioned between the coupling bowl (10) and the internal clamping element (5) which permits a relative movement of the coupling bowl (10) in relation to the clamping element (5).

According to the invention a coupling bowl (10) is supported on the internal clamping element (5) with adjustable pretension.
