The present invention relates to a method for moment transmission, preferably torque transmission, between a first object (4) and a second object (5) that are separated by a gap (g), the method comprising the arranging in said gap (g) of a force-transmitting device (1) that comprises at least one flexible element (3A, 3B) and a plurality of force-transmitting elements (2) that are not part of the flexible element (3A, 3B) but are arranged at said flexible element (3A, 3B), which force-transmitting elements (2) are arranged to have a maximum cross-sectional dimension (amax) that is larger than the gap (g) and another cross-sectional dimension (a) that is smaller than the gap (g), in order by friction by wedge-action to transmit moments between said first object (4) and said second object (5), said elements (2) being arranged to have a design and an attachment at said flexible element (3A, 3B) that without external influence of said device (1) enable transmission of force in two opposite directions. The invention also comprises such a device.
