Sh. Muḥammad b. Ṣāliḥ al-ʿUthaymīn, may Allāh have mercy upon him, said:

“al-Tiwalah is something [people] do claiming that it causes a woman to be loved by her husband and vice versa. The closest [term] to that is what is referred amongst us as al-diblah (ring). It is said that the husband inscribes his wife’s name in his ring, and the wife inscribes her husband’s name in her ring, and they claim that they – the couple – attain love and affection through this action of theirs, and that if he removes the ring, or she removes it, it means [their] separation.

So, if one asks: what is the means for a man to love his wife and his wife to love her husband? We say: the means to that has been explained by Allāh in His statement: {And live with them in a good manner} [al-Nisāʾ (4): 19]. So, if a person lives in a good manner with his wife, and she does likewise; love, closeness and blissful married life occurs.”

Note:

One of the many notable and beneficial features of Sh. al-ʿUthaymīn’s works, is that he always tries to provide a divinely legislated solution, and alternative, to something which is prohibited in the Dīn. May Allāh bless him with all goodness.
