An assembly and a method for manufacturing an assembly for transmitting torque to an aircraft actuator. The assembly and method include a torque tube having a longitudinal axis and an end fitting. The ending fitting includes a connector portion and an engagement portion that is inserted into the torque tube. The engagement portion includes a first end adjacent the connector portion, a second end opposite the first end, and a coupling region between the first and second end that includes an outer coupling surface having an outer diameter and a continuous groove formed thereon. The continuous groove includes two axial grooves that extend along the outer coupling surface along the longitudinal axis and a first parallel groove that extends circumferentially about the longitudinal axis along the outer coupling surface that joins the two axial grooves.

A crimper includes a first arm that includes a first crimper die that defines a first tapered channel. The crimper also includes a second arm coupled to the first arm at a pivot connection. The second arm includes a second crimper die that defines a second tapered channel. The pivot connection enables the first arm and the second arm to rotate about the pivot connection from an open state to a closed state. The first arm and second arm rotate at an angle relative to one another to allow loading of the expandable medical device into the first tapered channel or the second tapered channel and to allow positioning of the expandable medical device relative to a delivery device. When transitioning, the first tapered channel and the second tapered channel form a chamber that is configured to crimp the expandable medical device from the uncompressed state to the compressed state.

A working head (1) for a compression or cutting tool (100) comprises a connecting portion (3) for a removable connection of the working head (1) with an actuation part (2) of the tool (100), two jaws (4) movable between an open position and a closed position to perform the compression or cutting, and a local storage (6) configured for storing one or more cumulative data representative of a stress history of the jaws (4), wherein the local storage (6) is fixed to the working head (1).

A device for modeling hairpins promoting insertion of winding sets of the hairpins on a stator or rotor to allow an increased filling of the slot space in an assembly of winding sets on the stator or rotor is provided. Application relates to electric stators or rotors, and any device using electric wires having any gauge.
