Problem with pymodbus - ModuleNotFoundError: No module named 'pymodbus.client.sync'

[stsxbel]

Good afternoon. I installed a new server, installed pymodbus via pip, uploaded my scripts that worked on the old server, but when I start it, I get an error: ModuleNotFoundError: No module named 'pymodbus.client.sync'

import struct
import sys
import time
import datetime
import pymysql.cursors
from pymodbus.client.sync import ModbusSerialClient
from pymodbus.exceptions import ModbusIOException
from datetime import datetime

Look at doc as it can have changed.
Test.

>>> from pymodbus.client.sync import ModbusSerialClient
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pymodbus.client.sync'

No module named 'pymodbus.client.sync'
>>>
>>> # No sync
>>> from pymodbus.client import ModbusSerialClient
>>>
