A subsurface safety valve for a wellbore for production of fluids from a subsurface formation comprises a drive portion and an actuator portion. The drive portion comprises a first magnet assembly and the actuator portion comprises a second magnet assembly that is magnetically coupled to the first magnet assembly. At least one of the first magnet assembly or the second magnet assembly comprises a spatially rotated array of magnets arranged such that a magnetic field emitted from an operative side of the spatially rotated array of magnets facing a magnetic coupling is non-zero and such that the magnetic field emitted from a non-operative side of the spatially rotated array of magnets that is opposite the operative side is about zero.
