10 . The furniture drive according to claim 1 , wherein the first component and the second component are arranged relative to each other in the coupled position when the torque is below the limit torque, and are arranged in a decoupled position when the torque is above the limit torque, and

wherein the first and second components, in the decoupled position, are further spaced apart from each other in a direction extending transversely to the longitudinal direction of the first component than in the coupled position.

11 . The furniture drive according to claim 1 , wherein the adjustment element and the first component or the second component are formed together so as to have an integral one-piece configuration, or

wherein the adjustment element and the first and second components are separate from each other.

12 . The furniture drive according to claim 1 , wherein the adjustment element includes an actuating contour.

13 . The furniture drive according to claim 1 , wherein the furniture drive:

includes an actuating arm assembly having at least one movably-supported actuating arm for moving the movable furniture part;

includes a spring for applying a force to the actuating arm assembly, wherein the spring is connected to the actuating arm assembly via an engagement location; and

wherein upon a rotation of the adjustment element, a relative position of the engagement location with respect to the actuating arm assembly is adjustable.

14 . The furniture drive according to claim 13 , further comprising a threaded portion having a longitudinal direction, wherein the engagement location of the spring along the threaded portion is adjustable by rotating the adjustment element about a rotational axis.

15 . An item of furniture comprising:

a furniture carcass;

a furniture part movably-supported relative to the furniture carcass; and

the furniture drive according to claim 1 for moving the movable furniture part.

16 . The furniture drive according to claim 4 , wherein the first component and the second component are connected to each other via at least one film hinge.

17 . The furniture drive according to claim 6 , wherein the at least one spring:

is at least partially ring-shaped; or

is configured as an O-ring; or

is at least partially hollow cylindrical;

has a width between 0.1 mm and 3.0 mm; or

has a wall thickness between 0.1 mm and 2.0 mm; or
