Claim 24:
25. A tool coupling (20) extending in a forward-to-rearward direction (DF, DR) along a longitudinal axis (A1), and comprising:
a forward component (22) having a first body portion (28) and a male clamping portion (30) extending from a rear mating end (32) of the first body portion (28) in the rearward direction (DR), the male coupling portion (30) comprising a male hook (31) projecting in the rearward direction (DR);
a rear component (24) having a second body portion (34), a female clamping portion (36), and an inner cavity (38), the female clamping portion (36) opening out to a forward mating end (40) of the second body portion (34) and the inner cavity (38) communicating with the female clamping portion (36); and
a clamp (26) located in the inner cavity (38), the clamp (26) having a clamp forward engagement portion (42) and a clamp rear drive portion (44), the clamp forward engagement portion (42) comprising a clamp hook (43) which projects in the forward direction (DF);
wherein;
the male clamping portion (30) occupies the female clamping portion (36); and
upon actuation of a screw member (104) operatively engaged to the clamp rear drive portion (44), the tool coupling (20) is adjustable between
a fastened state in which:
the clamp hook (43) is engaged to the male hook (31); and
a rear mating surface (58) of the rear mating end (32) makes clamping contact with a forward mating surface (60) of the forward mating end (40);

an unfastened state in which:
the clamp hook (43) is disengaged from the male hook (31), and wherein:
actuation of the screw member (104) about a screw axis (A4) results in rotation of the clamp (26) about a swivel axis (A5) transverse to the longitudinal axis (A1); and
the swivel axis (A5) is not fixed relative to the rear component (24).
