A coupling arrangement for a gas turbine engine. The arrangement comprises first, second and third members. The first member has a first threaded mating surface extending in a first direction (X) and a flange extending in a direction generally normal to the first direction (X). The second member has a second threaded mating surface extending in the first direction (X) and a flange extending in a direction generally normal to the first direction (X), the flanges of the first and second members engaging against one another. The third member has a third threaded mating surface configured to engage against the first threaded mating surface, and a fourth threaded mating surface configured to engage against the second threaded mating surface.

A package of laminations includes a plurality of lamella segments, which are arranged in layers and embodied to be connected together as ring segments. Each of the lamella segments has a plurality of cutouts and at least one of the lamella segments has at least three cutouts. The lamella segments are interconnected via sleeves. A method for manufacturing a package of laminations, a multi-plate coupling employing the package of laminations and an industrial application using the disclosed type of coupling are also described.

A rotary operating element for operating a ventilation nozzle in an automobile passenger compartment. The rotary operating element includes a first rotation body and a second rotation body, which are held against one another in a form-locked manner by tensioning elements. The tensioning elements are disposed spaced radially apart from a rotary operating element longitudinal axis and, starting at a particular torque threshold value, the form fit between the first and second rotation bodies is released, whereby the ventilation nozzle to be operated is protected against damage and/or faulty operation.

A shear section for a rotating arrangement includes an axially-extending shaft having a connection flange and a coupling flange adjacent the connection flange. The coupling flange includes an annular shoulder portion and an elongated neck portion extending axially away from the shoulder portion and disposed concentrically within the shaft. The shear section further includes a plurality of fasteners extending axially through the shoulder portion and the connection flange, and securing the shaft to the coupling flange. Each of the plurality of fasteners includes a shank region and a reduced thickness portion circumscribing the shank region.

A propeller shaft includes a shaft part and a a first yoke having a fixing portion, a connecting portion, a first yoke portion and a first concave portion. The connecting portion is provided apart from a first concave portion in the direction of the rotation axis of the shaft part. An outside diameter of the connecting portion is greater than an outside diameter of the shaft part in a radial direction of the rotation axis of the shaft part.
