A reeling device 2 for coiling and uncoiling a payload cable 4 has an axial shaft 8, a reel 10 mounted on the axial shaft 8 and a nut member 12 with at least one roller 14,16 mounted on the nut member 12. The reel 10 has an outer surface, with a helical groove 11, about which a length of cable 4, 6 can be wrapped. The nut member 12 surrounds the reel 10 and is radially spaced from the outer surface of the reel 10 with the rollers 14, 16 rotating while engaging the helical groove 11. The rollers 14, 16 have a radial plane P which is inclined, possibly at an angle of 5 to 60 degrees, relative to a direction which is perpendicular to the longitudinal direction of the axial shaft 8. There may be a greater number of tension rollers 14 than retract rollers 16.
