1. A device for driving actuators for a thrust reverser comprising: a casing,a motor shaft adapted to be connected to a flexible drive shaft of the actuators, the motor shaft being rotatably mounted relative to the casing,a power drive unit comprising a motor adapted to rotatably drive the motor shaft,a brake movable between a clamped configuration wherein the brake prevents rotation of the motor shaft and a loosened configuration wherein the brake allows rotation of the motor shaft,a manual drive unit,a clutch comprising a clutch part movable between an engaged position wherein the manual drive unit is engaged with the motor shaft to rotatably drive the motor shaft, and a disengaged position wherein the manual drive unit is not engaged with the motor shaft, anda control part actuatable by an operator, the control part being movable relative to the casing between a powered drive position and a manual drive position, displacement of the control part from the powered drive position to the manual drive position causing displacement of the clutch part towards the engaged position to engage the manual drive unit with the motor shaft, and displacement of the brake towards the loosened configuration to allow a rotary drive of the motor shaft by the manual drive unit. 2. The device according to claim 1, wherein displacement of the control part from the powered drive position to the manual drive position first causes displacement of the clutch part towards the engaged position then displacement of the brake towards the loosened configuration. 3. The device according to claim 1, wherein the manual drive unit comprises a wheel rotatably moveable relative to the casing and the clutch part is rotationally fixed to the motor shaft and movable in translation relative to the motor shaft between the engaged position wherein the clutch part is engaged with the wheel (32) so as to make the motor shaft rotationally fixed to the wheel, and the disengaged position wherein the clutch part is not engaged with the wheel so as to detach the motor shaft from the wheel. 4. The device according to claim 1, wherein the manual drive unit comprises a wheel rotatably movable relative to the casing and the clutch part is rotationally fixed to the wheel and movable in translation relative to the wheel between the engaged position wherein the clutch part is engaged with the motor shaft so as to make the motor shaft rotationally fixed to the wheel, and the disengaged position wherein the clutch part is not engaged with the motor shaft so as to detach the motor shaft from the wheel. 5. The device according to claim 1, wherein the clutch comprises a spring arranged to urge the clutch part towards the engaged position. 6. The device according to claim 1, wherein the control part is rotatably movable relative to the clutch part about an axis of rotation parallel to a direction of displacement of the clutch part. 7. The device according to claim 6, wherein the control part comprises a ramp on which the clutch part is supported, the ramp being configured such that rotation of the control part relative to the clutch part causes translation of the clutch part between the engaged position and the disengaged position. 8. The device according to claim 1, wherein the brake comprises a first brake disc rotationally fixed to the casing and a second brake disc rotationally fixed to the motor shaft, and wherein the control part comprises flexible blades arranged, when the control part is in manual drive position, to urge the second brake disc by moving the second brake disc away from the first brake disc. 9. The device according to claim 1, wherein the control part is rotatably movable relative to the clutch part about an axis of rotation orthogonal to a direction of displacement of the clutch part. 10. The device according to claim 9, wherein the control part has a domed cam surface adapted to urge the clutch part towards the engaged position when the control part is in manual drive position. 11. The device according to claim 1, further comprising a control lever fixed to the control part, the lever being adapted to be gripped by an operator to allow the operator to manoeuvre the control part. 12. The device according to claim 1, wherein the manual drive unit comprises an input shaft rotatably movable relative to the casing. 13. The device according to claim 12, wherein the input shaft of the manual drive unit has an end shaped for being temporarily connected to a screwing and unscrewing tool to rotatably drive the input shaft. 14. The device according to claim 12, wherein the manual drive unit comprises a lockpin fixed to the input shaft, the casing has a housing for receiving the lockpin, and the input shaft is movable in translation relative to the casing between a locked position wherein the lockpin is received in the housing so as to prevent rotation of the input shaft and an unlocked position wherein the lockpin is out of the housing so as to allow rotation of the input shaft. 15. The device according to claim 14, wherein the manual drive unit comprises a spring arranged to urge the input shaft towards the locked position. 16. The device according to claim 12, wherein the manual drive unit comprises a first gear wheel rotationally fixed to the input shaft and a second gear wheel meshing with the first gear wheel, and wherein in the engaged position of the clutch part, the second gear wheel is rotationally fixed to the motor shaft via the clutch part, and in the disengaged position, the second gear wheel is detached from the motor shaft. 17. The device according to claim 1, comprising a housing and a locking pin adapted to be inserted into the housing when the control part is in the manual drive position so as to prevent displacement of the control part relative to the casing. 18. The device according to claim 17, wherein the locking pin is slidably mounted on the control part between a retracted position wherein the locking pin extends inside the control part and a locking position wherein the locking pin protrudes out of the control part. 19. The device according to claim 17, comprising a spring arranged to urge the locking pin towards the locking position. 20. An actuator assembly for thrust reverser, comprising: a plurality of actuators adapted to actuate a movable cowl of the thrust reverser,a driving device according to claim 1, anda plurality of flexible shafts connecting the motor shaft of the driving device to the actuators to transmit rotation from the motor shaft to the actuators so as to cause deployment or retraction of the actuators.
