  "textContent": "The present invention relates to a valve device (1) for controlling a fluid flow, comprising a valve housing (2) which encloses a channel section (7) that can be traversed by the fluid flow, a flap (3) which is pivotably arranged about a pivot axis (10) in the valve housing (2) for controlling a flowable cross-section (9) of the channel section (7), an actuating device (4) for driving the flap (3), which has a drive shaft (11), a coupling device (5) which couples a flap shaft (14) rigidly connected to the flap (3) and extending coaxially to the pivot axis (10) with the drive shaft (11) aligned coaxially to the pivot axis (10), such that it converts linear movements (12) of the drive shaft (11) into rotational movements (15) of the flap shaft (14). For this purpose, the coupling device (5) comprises a guide housing (41) with a screw guide (36) which has a helical guide groove (19) with two facing guide surfaces (20) and a sliding body (37) engaging in the guide groove (19), wherein the guide housing (41) is rigidly connected to the flap shaft (14) and the respective sliding body (37) is rigidly connected to the drive shaft (11). Reduced wear is achieved when the respective sliding body (37) is oriented helically complementary to the respective guide groove (19) and has two mutually opposing sliding surfaces (22) for planar contact with one of the guide surfaces (20).",
