The manoeuvring component (7-9) supports at least a first coupling component (17) for drive fluid, and when it locks and/or retains the tool the first coupling component is connected with a second coupling component (26) for drive fluid supported by the tool. - The second and/or first coupling component are/is displaceably fitted on the tool or manoeuvring component in order to maintain a gap-free connection between the two coupling components. |
