The present invention concerns a detent and/or a driving pawl (13, 15) for a slack adjuster (3) of a coupling device (1) for locking and/or rotating a pivoted drive pinion (11) provided on a spindle drive (10) acting on a rotating adjustment ring (7), said drive pinion having a toothed structure (12), wherein the detent and/or driving pawl (13, 15) has at least two pawl tongues (14, 16), which can be alternately meshed with the toothed structure (12) of the drive pinion (11), and the pawl tongues (14, 16) are cut at least partially by laser or water jet. The method further relates to a coupling device (1) and a method for producing a detent and/or driving pawl (13, 15).
