Force transmission device for variable valve drive

A force transmission device for a variable valve drive of an internal combustion engine with at least one gas exchange valve and with a camshaft having a first cam and a second cam, the force transmission device comprising:

• a first lever device configured to produce an operative connection between the first cam and the at least one gas exchange valve, wherein the first lever device has a first cam follower configured to contact the first cam and a first receptacle for the first cam follower, the first cam follower configured to be alternately displaceable or locked within the first receptacle;
• and
• a second lever device configured to produce an operative connection between the second cam and the at least one gas exchange valve, wherein the second lever device has a second cam follower configured to contact the second cam and a second receptacle for the second cam follower, the second cam follower configured to be alternately displaceable or locked within the second receptacle,
• wherein the first lever device is formed as a center-pivot rocker lever, or the second lever device is formed as a center-pivot rocker lever.
