1. A torque transfer device in the power train of a motor vehicle, for transferring torque between a drive unit (3) and a transmission input shaft (35) that is rotatable around an axis of rotation (12) for the transmission input shaft, having a hydrodynamic torque converter (6), which includes a converter cover (14) that is connectable to or connected to the drive unit (3), which converter cover may be coupled via an impeller (20) to a turbine wheel (21) to transfer torque, which turbine wheel is bridgeable, to transfer torque, by a torque converter lockup clutch (48), which includes a piston (56) that is movable to a limited extent in the axial direction and is constructed as a multi-plate clutch with a plate pack (50) that includes outer plates which are connected to an outer plate carrier (52) in a rotationally fixed connection, and inner plates which are connected to an inner plate carrier (46) in a rotationally fixed connection, the torque transfer device including: a guide piece (40) permanently non-rotatably connected to the converter cover and arranged to directly contact and guide the transmission input shaft;a coolant conducting device (44) permanently non-rotatably connected to the guide piece (40);a first coolant channel at least partially disposed between the coolant conducting device and the piston;at least one through-hole (100) in the guide piece, the at least one through-hole wholly enclosed by the guide piece in a radial direction orthogonal to an axis of rotation for the torque converter and including: a first end in the guide piece opening directly into the first coolant channel; and,a second end, wherein:the inner plate carrier is permanently non-rotatably connected to the coolant conducting device when the converter clutch is open; and,a line parallel to an axis of rotation for the torque converter passes through the through-hole and the first and second ends of the through hole without touching the guide piece. 2. The torque transfer device recited in claim 1, wherein the first coolant channel runs in the axial direction between the coolant conducting device (44) and the piston (56). 3. The torque transfer device recited in claim 2, wherein the first coolant channel extends from the plate pack (50) between the coolant conducting device (44) and the piston (56) radially inward to the guide piece (40). 4. The torque transfer device recited in claim 2, wherein the first coolant channel is connected with a second coolant channel through the at least one through-hole in the guide piece (40). 5. The torque transfer device recited in claim 4, wherein the through-hole (100) extends in the axial direction toward a damper hub (33). 6. The torque transfer device recited in claim 1, wherein the inner plate carrier (46) is attached to the coolant conducting device (44). 7. The torque transfer device recited in claim 1, wherein the outer plate carrier (52) is connected in a rotationally fixed connection to an input part (54) of a torsional vibration damping device (28), through which the outer plate carrier (52) is coupled with a damper hub, which is connected to the shaft (35) in a rotationally fixed connection. 8. The torque transfer device recited in claim 7, wherein a seal contact area (91; 101) is provided between the guide piece (40) and the damper hub (33). 9. The torque transfer device recited in claim 1, wherein the hydrodynamic torque converter (6) includes a three-channel system, through which the operation of the torque converter lockup clutch (48) is controlled. 10. A torque transfer device in the power train of a motor vehicle, for transferring torque between a drive unit (3) and a transmission input shaft (35) that is rotatable around an axis of rotation (12) for the transmission input shaft, having a torsional vibration device including an input part, an output part non-rotatably connected to a damper hub arranged to contact the shaft and transfer torque to the shaft, and an energy storage element engaged with the input and output parts for the torsional vibration damper, a hydrodynamic torque converter (6), which includes a converter cover (14) that is connectable to or connected to the drive unit (3), which converter cover may be coupled via an impeller (20) to a turbine wheel (21) to transfer torque, which turbine wheel is bridgeable, to transfer torque, by a torque converter lockup clutch (48), which includes a piston (56) that is movable to a limited extent in the axial direction and is constructed as a multi-plate clutch with a plate pack (50) that includes outer plates which are connected to an outer plate carrier (52) in a rotationally fixed connection, and inner plates which are connected to an inner plate carrier (46) in a rotationally fixed connection, wherein: the inner plate carrier is permanently non-rotatably connected to a coolant conducting device when the converter clutch is open;the coolant conducting device is permanently non-rotatably connected to a guide piece;the guide piece is permanently non-rotatably connected to the converter cover and is arranged to directly contact and guide the shaft;a first coolant channel is at least partially disposed between the coolant conducting device and the piston;a first end of a through-hole in the guide piece opens directly into the first coolant channel;the through-hole includes a second end;the at least one through-hole is enclosed by the guide piece;a line parallel to an axis of rotation for the torque converter passes through the through-hole and the first and second ends of the through hole without touching the guide piece;the outer plate carrier is directly and non-rotatably connected to the input part of the torsional vibration damping device.
