Clutch
From Memory Alpha, the free Star Trek reference
The clutch was a part of 19th and 20th century Human automobiles.
When Tom Paris crashed his automobile in the Fair Haven holoprogram, he blamed it on a clutch malfunction. (VOY: "Spirit Folk")
The inhabitants of Sigma Iotia II used automobiles patterned after those found described in Chicago Mobs of the Twenties. Captain Kirk managed to operate one of those vehicles after remembering the relationship between the clutch and the gears. (TOS: "A Piece of the Action")
A Grenthemen water hopper was another mode of transportation that had a clutch. (TNG: "Peak Performance")
