1. Apparatus comprising:
a first coupling subassembly extending in an axial direction, the first coupling subassembly including a fitting arranged at an axial end of the first coupling subassembly; and
a rotational coupling element rotatably surrounding the first coupling subassembly and adapted to be engaged with the fitting such that the rotational coupling element is rotatable with respect to the fitting but axially engageable with the fitting to apply an axial compressive force to the fitting,
the fitting comprising a refractory metal and having a face with a first configuration such that when the fitting is received in a second fitting when the fitting and the second fitting are brought into axial engagement by rotation of the rotational coupling element, the fitting and the second fitting at least partially rotationally engage to inhibit axial rotation of the fitting with respect to the second fitting.
