Assemblies and methods are provided for use in coupling a component to an actuator, where the component includes a stem and a drive nut, and the stem is configured to be rotated by the actuator and to move linearly through an opening in the drive nut. The rotor is moveable between at least a locked position and an unlocked position by movement of the handle. Then, it is played back and displayed in a \u201cstill picture display area\u201d of the liquid crystal monitor, and is recorded as a still picture file in a memory card. Thus, in case of accidental ingress of water inside the submarine cable, the water flow inside the buffer tubes is prevented from reaching long penetration lengths by the hydrostatic pressure of the water inside the longitudinal cavity acting onto the outer surface of the buffer tube. To simplify the assembly, several cutouts distributed over the periphery are arranged in the connecting piece of the housing for engagement of an assembly tool, wherein the housing is connected to the connecting piece with a positive fit.
