The invention relates to a device permitting the rotation, about a vertical or horizontal shaft (1), of tubular portions (2) held on the shaft by rings (3) in a machined housing (4) and separated by spacers (5) which are themselves held on the shaft by screws (6). The rotary portions are perforated with tapped holes (7) which are diametrically opposed and positioned with normalised spacing (8).
