Locking device for mechanical and non-mechanical activation of a locking bolt, the locking device (10) comprising

• a locking bolt (12) having an extended position corresponding to a locked state and a retracted position corresponding to an unlocked state,
• a follower arrangement (30) comprising a follower arm (32) arranged to rotate about a first axis (B), the follower arm (32) being operatively connected to the locking bolt (12) for moving the locking bolt (12) in response to rotation of the follower arm (32),
• the follower arrangement (30) further comprising a follower (31) configured to rotate about the first axis (B) in response to mechanical activation of the locking device (10),
• the follower (31) operatively connected to the follower arm (32) such that rotation of the follower (31) causes rotation of the follower arm (32), and
• a non-mechanical activation unit (A) connected to a rod arrangement (40), said rod arrangement (40) configured to move in a first direction (D) in response to activation of the non-mechanical activation unit (A),
• said non-mechanical activation unit (A) connected to a first rod (41) of the rod arrangement (40) such that activation of the non-mechanical activation unit (A) causes movement of the first rod (41), wherein
• the locking device (10) comprises a coupler (50) for coupling the movement of the rod arrangement (40) in the first direction (D) to the follower arrangement (30) and causing rotation of the follower arm (32), and a play (P) configured to allow rotation of the follower arm (32) caused by mechanical activation without causing movement of the first rod (41) of the rod arrangement (40),
• wherein the play (P) is provided in the coupler (50) such that movement of the rod arrangement (40) in response to the non-mechanical activation is coupled to cause rotation of the follower arm (32), and rotation of the follower arm (32) in response to the mechanical activation is not coupled to the rod arrangement (40),
• wherein the coupler (50) comprises a coupling member (53) arranged to rotate about the first axis (B),
• said coupling member (53) having a second coupling portion (52) for engaging the rod arrangement (40) such se that movement of the rod arrangement (40) in the first direction (D) is coupled to the coupling member (53), and
• said coupling member (53) also having a follower arrangement engagement portion (P1) for engaging the follower arrangement (30) and coupling rotation of the coupling member (53) to the follower arrangement (30).
