1. Device for conducting hydraulic fluid from a first connection to a second connection via at least one conduit line, the device having a housing comprising a first housing part having the first connection and a second housing part having the second connection, which parts can be rotated relative to one another about an axis of rotation and have a hydraulic rotary union for transferring the hydraulic fluid, said first housing part having a central housing, said second housing part having a central body, and said central housing and said central body mutually engaging one another and being rotatably mounted relative to each another, each of the central housing and central body including at least one conduit arm characterized in a configuration for detachable attachment to a hydraulic torque motor having hydraulic connections separate from the device for hydraulic operation of the torque motor, the device laterally securable to the torque motor which comprises a first part and a second part pivotable relative to the first part wherein at least one respective conduit arm extends substantially radially away from the central housing and from the central body, in relation to the axis of rotation, and in that the second housing part comprises securing means associated with the second part of the torque motor.
