FIELD: machine building.
SUBSTANCE: invention relates to mechanical engineering, and more particularly to mechanised tools. Tubular device (30; 30a) for connecting to shaft (20) so that torque can be transmitted between said tubular device (30; 30a) said shaft (20) gas hollow accommodating region (38) for accommodating first bearing region (46) of shaft (20). Hollow accommodating region (38) has at least first contact surface (72) for coming into contact at least radially with at least first contact region (46) of shaft (20). Tubular device (30; 30a) has at least one torque-transmitting section which is provided for engaging with at least one torque-transmitting section (50.1, 50.2, 50.3, 50.4) of shaft (20). At least one torque-transmitting section of tubular device (30; 30a) is at least one elevation (39.1, 39.2, 39.3, 39.4) which is provided immovably on tubular device (30; 30a) and which projects from contact surface (72) into hollow accommodating region (38).
EFFECT: simplified assembly.
